FPGA boards come at different price points, with the price being a good indicator for how much logic the FPGA can hold. The following sections give details of how to obtain our supported FPGA boards.
The ChipWhisperer CW310 board is produced by NewAE Technology. It is available with a Xilinx Kintex 7 XC7K160T or XC7K410T FPGA. At the moment, the version with the smaller Xilinx Kintex 7 XC7K160T FPGA is not supported by OpenTitan. The ChipWhisperer CW310 board with the bigger Xilinx Kintex 7 XC7K410T FPGA is the main development FPGA board for OpenTitan.
The Nexys Video board features a Xilinx Artix 7 XC7A200T FPGA. The board is produced by Digilent.
You can get the Nexys Video board from the Digilent web store. Significant discounts are available for academic users (including students), see the Digilent academic price list for details.
Most large electronics distributors like Farnell/element14, RS Components, Mouser or Digikey list the board as well.
